Of these some are commemorative of historical events, and one at least may perhaps be regarded as a relic of ancestor-worship; but the great majority are nature-festivals, associating themselves in the manner that has already been indicated with the phenomena of the seasons, the equinoxes and the solstices.[9] In addition to their numerous public festivals, the Greeks held various family celebrations, also called ἑορταί, in connexion with weddings, births and similar domestic occurrences. For the great national πανηγύρεις—Olympian, Pythian, Nemean and Isthmian—see the article [Games, Classical].

Roman Festivals.—For the purpose of holding comitia and administering justice, the days of the Roman year were regarded as being either dies fasti or dies nefasti—the dies fasti being the days on which it was lawful for the praetors to administer justice in the public courts, while on the dies nefasti neither courts of justice nor meetings of comitia were allowed to be held. Some days were fasti during one portion and nefasti during another; these were called dies intercisi. For the purposes of religion a different division of the year was made; the days were treated as festi or as profesti,—the former being consecrated to acts of public worship, such as sacrifices, banquets and games, while the latter (whether fasti or nefasti) were not specially claimed for religious purposes. The dies festi or feriae publicae[10] were either stativae, conceptivae or imperativae. The stativae were such as were observed regularly, each on a definite day; the conceptivae were observed annually on days fixed by the authorities for the time being; the imperativae were publicly appointed as occasion called for them. In the Augustan age the feriae stativae were very numerous, as may be seen from what we possess of the Fasti of Ovid. The number was somewhat fluctuating. Festivals frequently fell into desuetude or were revived, were increased or diminished, were shortened or prolonged at the will of the emperor, or under the caprice of the popular taste. Thus Augustus restored the Compitalia and Lupercalia; while Marcus Antoninus in his turn found it expedient to diminish the number of holidays.

The following is an enumeration of the stated festivals as given by Ovid and contemporary writers. The first day of January was observed somewhat as is the modern New Year’s day: clients sent presents to their patrons, slaves to their masters, friends and relatives to one another. On the 9th the Agonalia were held, apparently in honour of Janus. On the 11th the Carmentalia were kept as a half-holiday, but principally by women; so also on the 15th. On the 13th of February were the Faunalia, on the 15th the Lupercalia, on the 17th the Quirinalia, on the 18th the Feralia, on the 23rd (at one time the last day of the Roman year) the Terminalia, on the 24th the Regifugium or Fugalia, and on the 27th the Equiria (of Mars). On the 1st of March were the Matronalia, on the 14th a repetition of the Equiria, on the 15th the festival of Anna Perenna, on the 17th the Liberalia or Agonalia, and from the 19th to the 23rd the Quinquatria (of Minerva). On the 4th of April were the Megalesia (of Cybele), on the 12th the Cerealia, on the 21st the Palilia, on the 23rd the Vinalia, on the 25th the Robigalia, and on the 28th the Floralia. The 1st of May was the festival of the Lares Praestites; on the 9th, 11th and 13th the Lemuria were celebrated; on the 12th the Ludi Martiales, and on the 15th those of Mercury. June 5 was sacred to Semo Sancus; the Vestalia occurred on the 9th, the Matralia on the 11th, and the Quinquatrus Minusculae on the 13th. The Ludi Apollinares were on the 5th, and the Neptunalia on the 23rd of July. On the 13th of August were the Nemoralia, in honour of Diana; on the 18th the Consualia, on the 19th the Vinalia Rustica, and on the 23rd the Vulcanalia. The Ludi Magni, in honour of Jupiter, Juno and Minerva, began on September 4. The Meditrinalia (new wine) were on the 11th of October, the Faunalia on the 13th, and the Equiria on the 15th. The Epulum Jovis was on 13th November. The December festivals were—on the 5th Faunalia, and towards the close Opalia, Saturnalia, Larentalia.

The calendar as it stood at the Augustan age was known to contain many comparatively recent accessions, brought in under the influence of two “closely allied powers, the foreign priest and the foreign cook” (Mommsen). The Megalesia, for example, had been introduced 204 B.C. The Ludi Apollinares could not be traced farther back than 208 B.C. The Floralia and Cerealia had not come in much earlier. Among the oldest feasts were undoubtedly the Lupercalia, in honour of Lupercus, the god of fertility; the Equiria, in honour of Mars; the Palilia; the great September festival; and the Saturnalia.

Among the feriae conceptivae were the very ancient feriae Latinae, held in honour of Jupiter on the Alban Mount, and attended by all the higher magistrates and the whole body of the senate. The time of their celebration greatly depended on the state of affairs at Rome, as the consuls were not allowed to take the field until they had held the Latinae, which were regarded as days of a sacred truce. The feriae sementivae were held in the spring, and the Ambarvalia in autumn, both in honour of Ceres. The Paganalia of each pagus, and the Compitalia of each vicus were also conceptivae. Of feriae imperativae,—that is to say, festivals appointed by the senate, or magistrates, or higher priests to commemorate some great event or avert some threatened disaster,—the best known is the Novendiale, which used to be celebrated as often as stones fell from heaven (Livy xxi. 62, xxv. 7, &c.). In addition to all those already mentioned, there occasionally occurred ludi votivi, which were celebrated in fulfilment of a vow; ludi funebres, sometimes given by private persons; and ludi seculares, to celebrate certain periods marked off in the Etrusco-Roman religion.

Feasts of the Jews.—By Old Testament writers a festival or feast is generally called either חג (compare the Arabic Hadj), from חגג to rejoice, or מועד, from יעד, to appoint. The words שבת and מקרא קודש are also occasionally used. In the Talmud the three principal feasts are called רגלים, after Exod. xxiii. 14. Of the Jewish feasts which are usually traced to a pre-Mosaic origin the most important and characteristic was the weekly Sabbath, but special importance was also attached from a very early date to the lunar periods. It is probable that other festivals also, of a seasonal character, were observed (see Exod. v. 1). In common with most others, the Mosaic system of annual feasts groups itself readily around the vernal and autumnal equinoxes. In Lev. xxiii., where the list is most fully given, they seem to be arranged with a conscious reference to the sacred number seven (compare Numb. xxviii.). Those belonging to the vernal equinox are three in number; a preparatory day, that of the Passover, leads up to the principal festival, that of unleavened bread, which again is followed by an after-feast, that of Pentecost (see [Passover], [Pentecost]). Those of the autumnal equinox are four; a preparatory day on the new moon of the seventh month (the Feast of Trumpets) is followed by a great day of rest, the day of Atonement (which, however, was hardly a festival in the stricter sense of the word), by the Feast of Tabernacles, and by a great concluding day (Lev. xxiii. 36; John vii. 37). If the feast of the Passover be excepted, it will be seen that all these celebrations or commemorations associate themselves more readily with natural than with historical events.[11] There was also a considerable number of post-Mosaic festivals, of which the principal were that of the Dedication (described in 1 Macc. iv. 52-59; comp. John x. 22) and that of Purim, the origin of which is given in the book of Esther (ix. 20 seq.). It has probably no connexion with the Persian festival Furdigán (see [Esther]).[12]

Earlier Christian Festivals.—While making it abundantly manifest that Christ and his disciples observed the appointed Jewish feasts, the New Testament nowhere records the formal institution of any distinctively Christian festival. But we have unambiguous evidence of the actual observance, from a very early period, of the first day of the week as a holy day (John xx. 19, 26; 1 Cor. xvi. 2; Acts xx. 7; Rev. i. 10). Pliny in his letter to Trajan describes the Christians of Bithynia as meeting for religious purposes on a set day; that this day was Sunday is put beyond all reasonable doubt by such a passage as that in the Apology of Justin Martyr, where he says that “on Sunday (τῆ τοῦ ἡλίου λεγομένῃ ἡμέρᾳ) all the Christians living either in the city or the country met together.” The Jewish element, in some churches at least, and especially in the East, was strong enough to secure that, along with the dies dominica, the seventh day should continue to be kept holy. Thus in the Apostolic Constitutions (ii. 59) we find the Saturday specially mentioned along with the Sunday as a day for the assembling of the church; in v. 15 it is ordained that there shall be no fasting on Saturday, while in viii. 33 it is added that both on Saturday and Sunday slaves are to have rest from their labours. The 16th canon of the council of Laodicea almost certainly means that solemn public service was to be held on Saturday as well as on Sunday. In other quarters, however, the tendency to regard both days as equally sacred met with considerable resistance. The 36th canon of the council of Illiberis, for example, deciding that Saturday should be observed as a fast-day, was doubtless intended to enforce the distinction between Saturday and Sunday. At Milan in Ambrose’s time Saturday was observed as a festival; but Pope Innocent is found writing to the bishop of Eugubium to urge that it should be kept as a fast. Ultimately the Christian church came to recognize but one weekly festival.

The numerous yearly festivals of the later Christian church, when historically investigated, can be traced to very small beginnings. Indeed, while it appears to be tolerably certain that Jewish Christians for the most part retained all the festivals which had been instituted under the old dispensation, it is not at all probable that either they or their Gentile brethren recognized any yearly feasts as of distinctively Christian origin or obligation. It cannot be doubted, however, that gradually, in the course of the 2nd century, the universal church came to observe the anniversaries of the death and resurrection of Christ—the πάσχα σταυρώσιμον and the πάσχα ἁναστάσιμον, as they were respectively called (see [Easter] and [Good Friday]). Not long afterwards Whitsunday also came to be fixed in the usage of Christendom as a great annual festival. Even Origen (in the 8th book Against Celsus) enumerates as Christian festivals the Sunday, the παρασκευή, the Passover with the feast of the Resurrection, and Pentecost; under which latter term, however, he includes the whole period between Easter and Whitsuntide. About Cyprian’s time we find individual Christians commemorating their departed friends, and whole churches commemorating their martyrs; in particular, there are traces of a local and partial observance of the feast of the Innocents. Christmas day and Epiphany were among the later introductions, the feast of the Epiphany being somewhat the earlier of the two. Both are alluded to indeed by Clemens Alexandrinus (i. 340), but only in a way which indicates that even in his time the precise date of Christ’s birth was unknown, that its anniversary was not usually observed, and that the day of his baptism was kept as a festival only by the followers of Basilides (see [Epiphany]).

When we come down to the 4th century we find that, among the 50 days between Easter and Pentecost, Ascension Day has come into new prominence. Augustine, for example, enumerates as anniversaries celebrated by the whole church those of Christ’s passion, resurrection and ascension, along with that of the outpouring of the Holy Ghost, while he is silent with regard to Christmas and Epiphany. The general tendency of this and the following centuries was largely to increase the festivals of the Church, and by legislation to make them more fixed and uniform. Many passages, indeed, could be quoted from Chrysostom, Jerome and Augustine to show that these fathers had not by any means forgotten that comparative freedom with regard to outward observances was one of the distinctive excellences of Christianity as contrasted with Judaism and the various heathen systems (compare Socrates, H.E. v. 22). But there were many special circumstances which seemed to the leaders of the Church at that time to necessitate the permission and even legislative sanction of a large number of new feasts. The innovations of heretics sometimes seemed to call for rectification by the institution of more orthodox observances; in other instances the propensity of rude and uneducated converts from paganism to cling to the festal rites of their forefathers proved to be invincible, so that it was seen to be necessary to seek to adapt the old usages to the new worship rather than to abolish them altogether;[13] moreover, although the empire had become Christian, it was manifestly expedient that the old holidays should be recognized as much as possible in the new arrangements of the calendar. Constantine soon after his conversion enacted that on the dies dominica there should be no suits or trials in law; Theodosius the Great added a prohibition of all public shows on that day, and Theodosius the younger extended the prohibition to Epiphany and the anniversaries of martyrdoms, which at that time included the festivals of St Stephen, and of St Peter and St Paul, as also that of the Maccabees. In the 21st canon of the council of Agde (506), besides Easter, Christmas, Epiphany, Ascension and Pentecost, we find the Nativity of John the Baptist already mentioned as one of the more important festivals on which attendance at church was regarded as obligatory. To these were added, in the centuries immediately following, the feasts of the Annunciation, the Purification, and the Assumption of the Virgin; as well as those of the Circumcision, of St Michael and of All Saints.

Festivals were in practice distinguished from ordinary days in the following ways: all public and judicial business was suspended,[14] as well as every kind of game or amusement which might interfere with devotion; the churches were specially decorated; Christians were expected to attend public worship, attired in their best dress; love feasts were celebrated, and the rich were accustomed to show special kindness to the poor; fasting was strictly forbidden, and public prayers were said in a standing posture.
